Working Principles

The 74LVQ374QSC is a latch-based flip-flop that can store and transfer data in digital circuits. It operates based on the clock pulse provided at the CP pin. When the clock pulse is active, the latch becomes transparent, allowing the data inputs (D0-D7) to pass through to the corresponding outputs (Q0-Q7). The latch captures and stores the data at the rising or falling edge of the clock pulse, depending on the specific application.
